The Lower North Shore supports 666 species of vascular plants. Moving east, the harsher climate and changing geology mean there are fewer species. Black spruce and bogs predominate on this barren land. In summer and fall, the ground is covered with a spongy carpet of fruit-bearing plants, wildflowers, lichens and mosses. Picking the many delicious wildberries is a local tradition. Berries that grow in the region include cloudberry (bakeapple), cranberry, crowberry (blackberry), partridgeberry (redberry), bunchberry and blueberry. Labrador tea, blue flag iris, and bog laurel are other common plants. Fernald’s milkvetch is a rare perennial that only grows in the Blanc-Sablon area and possibly on the Northern Peninsula of Newfoundland. It can be found on cliff tops and sides of limestone hills, where wind prevents snow accumulation and enables frost and thaw to strip away competing vegetation.
